Application filed January 21,1207, Serial No. 353,322.

To all whom it may concern:

Be it known that l', OnilANDo iwnns, a citizen of the United States,residing atlmigmont, 'in the county of Boulder and State of Colorado,have invented a new and usefu-l Wagon-Loading Device, oi which theiollovring is a specification.

This invention relates to a device for taking up 1naterials, such aswheat, potatoes, and the like, in sacks,

. and beets, or other similar material, in bulk, and transuse, andadapted to enable a man to pick up heavy objects and place thegn in anydesired place with considerablev ease and facility.

A further object of the invention is to provide a pair I of jawssuitably mounted upon a boom or lever which the operator controls from asuitable point, the jaws being opened and closed by anactuatingmechanism which is controllable from a point convenient to theoperator. Y

Another object of the invention is to so mount the lift- 'ing boomorlevcr that it can be raised and lowered by means of a jack devicecarried bythe stand onwhich the boom is inlcrumed.

With these objects in view, and others, as will appear'- as-the natureof the invention is better undexstood,the invention comprises thevarious novel features oi eonstruction and arrangement of parts, whichwill be more fully described hereinafter, and set forth withparticularity in the claims appended hereto. i

In the accompanying drawing, which illustrates one of the embodiments ofthe invention, Figure 1 is a pers ective View of Vthe loadin deviceshowin f a ortion P g s P o the column of the stand broken away toillustrate the' details oi the jack device. Fig. 2 yis a fragmentaryside elevation 0i the operators controlling device for the jaw operatingmechanism. Fig. 3 is av transverse section of the handle end of theliitingever showing the jaw actuating device. Fig. 4 is a side elevationof the beef gathering jaws. Fig. 5 is`a 'transverse section j thereof.

Corresponding parts in 'the several figures are indicated throughout bysimilar characters of reference. Referring to the drawing, l.designatesthe lifting lboom or lever ofthe apparatus which is hinged at2 on the upper end of alvertically disposed pivot 3 mounted inthe stand,designated generally by 4. The stand compris-es a hollow column 'or post5 provided at its i lower end with asuitablcbasc, such, for instance, as

l i l l i i i I be moved about the vertical axis oi the legs l, wherebythe upright or column 5 is supported in a vertical position. The pivot 3is provided with a shoulder or collar? which is adapted, when the leverl is in its lowcrini'ist position, to bear on the upper end oi theupright 5. By this means, the lifting llever 1 can stand and also tiltedon the horizontal pivot 2.

ln some circumstances, it may be desirable to vary the height oi thepivot 2 on which the lifting lcvcr 1 load wagons of different heights.For thispurpose, a mechanism for adjusting the pivot 3 is employed,y thesaine comprising a pawl 8 having ahandle 9 and. ar-

ranged to engage ratchet teeth lOpn the pivot 3, a spring actuated pawll1 cooperating with the pawl 9 to permit the pivot'irto he raised orlowered step by step.

swings, as, for instance, to accommodate the device to The pawls arefulerumed on lugs 12 formed on the up- -right 5, and adjacent the lugsare slots 13into which the pawls extend to.eugage`the ratchet teeth onthe pivot. The pawl 8 is provided with a slot 14 through which thefulcrum pin 15 extends, the slot permitting of the pawl beingmoved backand orth as it is worked from one tootlrt'ol another. In order to permitthe pivot 3 to be turned, while itis held in position by the pawl 11,the ratchet teeth l0 are circular and extend entirely around thelpivot.By means of this jack device, the

lifting leveror boom 1 can be readily and conveniently l' raiscd'orlowered on the supporting stand 4 to any de,

' sired position.

The lifting lever or boom 1, which may be of any desired constructionand of suitable proportions, carries at one end a pair of scooped-shapedjaws 16 which are approximately semi-cylindrical in shape and hingedtogether at 17. Each jaw is provided with an arm 18 arranged at themiddle thereof and extending between the bifurcations 19 of the lever l.The .jaws are so arranged that the arms 18 cross each other aiterthefashion oi a pair of tongs, and are hinged to the lever 1 by the pin 20.The upper ends of the arms 18 are connected by toggle links 2l which arestraightened and collapsed by the bell crank lever 22 fuleruinecl onthe,

lever 1 adjacent the jaw carrying end.. The tilting of the'boll cranklever 22 actuatcs the toggle links 21 so that the jaws 16am eitheropened or closed, so that articles can be picked up thereby anddeposited. The bell crank lever is actuated by a pitman or connectingrod 23 which extends approximatelyfrom one endof the connecting lever lto the other. At the end of the lever 1 opposite from that carrying thejaw 16 is a handle 24, and adjacent this handle is a controlling device,designated generally by 25,1`for moving the pitman 23 longitudinallyhack and forth to open and close the jaws. This controlling devicecomprises an arm 26 iulcrumed at 27 on the handle end of the lever 1 andpivoted at 28 to the pitman. Hence, by oscillating the ar1n'26, thepitman will be moved in one direction or the other. In order to lock thearm 26 in eitiher of its two positions and thus hold the jaw 16 open orclosed, the latch 29 is i'ulcrumed at 30 on a lug 3l formed on the Thelatch is provided with a projection 32 which-engages in the upperopening or depression 33 when the jaws are open, and in the lower'opening or depression 34 when the jaws have been moved to closedposition, as shown respectively by the full and dotted lines in Fig. 2.v

When the lever l has been adjusted to such a height that it is notconvenient for the operator to reach the handle 2o, the said lever canbe moved by the operator taking hold )if the auxiliary or secondaryhandle 35.

' The said auxiliary handle comprises a vertically ex,-

tending inomlierti that is ',treelymovable through an aperture in thehandle 24f/'and at its lower end carries a grip mornber lor lrandhold37. On the upper end oi the member 36 is aprojeetion 38 forming a stopfor preventing the auxiliary handle from pulling out.

in, operation, the lever' l. is first adjusted by means of the jackdevice on the stand 4 to the desired position, and the stand is placedin suitable proximity to the wagonor other place where the material isto be doposited, and also in suitable proximity to the material to betaken up by the device and transferred to the wagon. ll`he operator thentakes the main or auxiliary v handle oi the lever' in one hand and withthe other operates the latch 29 and cout roller arm 2G. By loosening thelatch and throwing thc arm 2G toward the stand 4, the jaws are opened bythe intervening connections. 'lhe lever' l is next tilted so that thejaws can take upa sack or any bulk material on the ground and the latchis again released and the arm 2G swung in thc opposite direction. llythis operation, the jaws are closed upon a sack or whatever otherobject-is to be lifted. The operator then pulls down on the handle endol' 'the lever l and at the same time swings the lever around on thepivot 3 as an axle so as to throw the jaw end of the lever over the bodyol the wagon into which the jaws are to empty. While being held in thisposition, the latch 29 is again released, and the arm 2G moved towardthev stand 4, thus causing the jaws to open and the contents thcreol tobe deposited into the wagon. The lover l is then swung back and loweredto itsvinitial position to take up another sack and transportit to thewagon, and so on, imlcfinitely.I It will thus be seen that/thelittingand transporting oi' suitablelmaterial from -place to place can beconveniently and (prickly accomplished by means oi the iinproved device.

The preferred form oi jaws for use with the apparatus when handlingbeets and similar loose products is slroW-n in Figs.A ll` and 5. Thesejaws each comprise a plurality ol spaced curved teeth connected orformed integral with a cross bar 40, and the inner' ends o the teethIl!) ol both jaws overlap and are connected by a pintle 4| so as tohinge open or closed. The central teeth are provided with arms 42through which the pintle passes, and these arms serve to connect thejaws with the toggle links 2l of the device. These beet gathering jawsand the sack gathering jaws Shown in Fig. lare intended to be usedinterchangeably, and to detach one set of jaws and apply the other, itis merely necessary to remove the pins 4.3, Fig. l, which connect thearms of the jaws with the toggle links 2l., and substitute the jawsdesired.
